Obsessive-Compulsive and Related Disorders Practice Questions

Q: What is Trichotillomania?

Compulsive hair pulling. ***Compulsive hair pulling*** - **Trichotillomania** is characterized by an irresistible urge to **pull out one's own hair**, often leading to noticeable hair loss. - It is classified as an **obsessive-compulsive related disorder** in the DSM-5. *Irresistible desire to set fire to things* - This describes **pyromania**, a distinct impulse control disorder. - While both are impulse control disorders, their specific behaviors and focus are different. *Irresistible desire to steal* - This refers to **kleptomania**, an impulse control disorder characterized by recurrent urges to steal objects not needed for personal use or monetary value. - It is distinct from trichotillomania, which involves self-inflicted harm through hair pulling. *Compulsive gambling* - This is known as **gambling disorder**, an addictive disorder involving persistent and problematic gambling behavior. - It involves financial risk and reward and is not related to hair pulling.

Q: Which personality disorder is most commonly associated with Obsessive-Compulsive Disorder (OCD)?

Anankastic Personality Disorder. ***Anankastic Personality Disorder (Obsessive-Compulsive Personality Disorder)*** - Anankastic Personality Disorder is the **ICD-10 classification** for what is known as **Obsessive-Compulsive Personality Disorder (OCPD)** in the DSM-5. - **Important distinction**: OCD and OCPD are **separate disorders** - OCD is an anxiety disorder with intrusive thoughts and compulsions, while OCPD is a personality disorder characterized by rigid perfectionism and need for control. - OCPD is the **most commonly comorbid personality disorder** with OCD, though most people with OCD do not have OCPD and vice versa. - Individuals with OCPD show a pervasive pattern of **preoccupation with orderliness**, perfectionism, and mental and interpersonal control, at the expense of flexibility, openness, and efficiency. *Borderline Personality Disorder* - Characterized by **instability in interpersonal relationships**, self-image, affects, and marked impulsivity. - While it can be comorbid with anxiety disorders, its core features are distinct from the rigid and perfectionistic traits of OCPD. *Narcissistic Personality Disorder* - Involves a pervasive pattern of **grandiosity**, a need for admiration, and a lack of empathy. - These traits are distinct from the compulsive behaviors and perfectionism seen in OCD and OCPD. *Histrionic Personality Disorder* - Defined by a pattern of **excessive emotionality** and attention-seeking behavior. - This presentation is quite different from the rigid, controlling, and overly conscientious nature associated with OCD.

Q: Pyromania is characterized by an irresistible urge to engage in which of the following behaviors?

Set objects on fire. ***Set objects on fire*** - Pyromania is a **mental disorder** characterized by a powerful, **irresistible urge to start fires**. - The individual experiences **tension or arousal** before the act, followed by **pleasure, gratification, or relief** after setting a fire or witnessing its effects. - This is classified as an **impulse control disorder** in psychiatric nosology. *Overeat* - This behavior is characteristic of **eating disorders** such as **binge eating disorder** or **bulimia nervosa**, not pyromania. - While impulses are involved, the specific urge and gratification are linked to food consumption, not fire-setting. *Excessive sleeping* - **Hypersomnia** or **excessive daytime sleepiness** is a symptom of various sleep disorders or medical conditions, not an impulse control disorder. - There is no direct association between the urge to sleep excessively and the diagnostic criteria for pyromania. *Steal items* - This behavior is characteristic of **kleptomania**, another impulse control disorder. - While both pyromania and kleptomania involve irresistible urges, kleptomania specifically involves stealing objects not needed for personal use or monetary value.

Q: In which condition is psychosurgery considered as a last resort treatment?

Severe Obsessive-Compulsive Disorder. ***Severe Obsessive-Compulsive Disorder*** - Psychosurgery (e.g., **anterior cingulotomy**, **capsulotomy**) is considered for individuals with **severe, refractory OCD** who have not responded to conventional treatments. - This intervention aims to disrupt specific neural circuits implicated in OCD, such as the **corticostriatothalamocortical (CSTC) loop**. *Severe Generalized Anxiety Disorder* - While GAD can be debilitating, standard treatments like **psychotherapy (CBT)** and **pharmacotherapy (SSRIs, SNRIs)** are generally effective. - Psychosurgery is not typically considered for GAD, as less invasive and established treatments carry significantly lower risks. *Severe Depression* - For severe, treatment-resistant depression, **electroconvulsive therapy (ECT)** and **transcranial magnetic stimulation (TMS)** are more common and established interventions. - Psychosurgery is rarely, if ever, used for severe depression due to ethical concerns and the availability of less invasive options. *Severe Phobia* - Severe phobias primarily respond to **exposure therapy** and **cognitive behavioral therapy (CBT)**. - These therapies directly target the learned fear response and are highly effective without the need for invasive procedures.

Q: What term describes repetitive, intrusive thoughts that cause significant distress or anxiety?

Obsession. ***Obsession*** - An **obsession** is defined by the presence of **recurrent and persistent thoughts, urges, or images** that are experienced as intrusive and unwanted, causing significant anxiety or distress. - These thoughts are often recognized as products of one's own mind, and individuals typically attempt to ignore, suppress, or neutralize them. *Phobia* - A **phobia** is an intense, irrational fear of a specific object or situation that poses little or no actual danger. - Unlike obsessions, phobias are typically related to external stimuli and do not primarily involve intrusive thoughts. *Compulsion* - A **compulsion** is a repetitive behavior (e.g., hand washing, checking) or mental act (e.g., praying, counting) that an individual feels driven to perform in response to an obsession. - Compulsions are often aimed at preventing or reducing anxiety or distress, or preventing some dreaded event or situation. *Anxiety* - **Anxiety** is a general term for a feeling of worry, nervousness, or unease, typically about an event or something with an uncertain outcome. - While obsessions cause anxiety, "anxiety" itself is a broad emotional state, not specifically the intrusive thoughts described.

Q: A patient presents with compulsive hair pulling resulting in irregular patchy hair loss. What is the most likely diagnosis?

Trichotillomania. ***Trichotillomania*** - This condition is characterized by **recurrent, irresistible urges to pull out hair**, typically resulting in **noticeable hair loss**. - The resulting patchy hair loss is often **irregular** and can occur in various areas, aligning with the patient's presentation. *Alopecia areata* - This is an **autoimmune condition** that causes smooth, **well-demarcated patches of hair loss**, not typically associated with compulsive pulling. - It usually presents with a sudden onset of hair loss without any preceding trauma or manipulation. *Telogen effluvium* - This condition involves **widespread hair thinning** due to a disturbance in the hair growth cycle, often triggered by stress or illness. - It does not involve compulsive hair pulling and typically results in increased hair shedding rather than patchy hair loss. *Tinea infection* - Also known as **ringworm**, this is a fungal infection that can cause **scaly, itchy patches of hair loss**, sometimes with inflammation and broken hairs. - While it can cause patchy hair loss, it is characterized by dermatological signs of infection (e.g., scaling, erythema) and not compulsive hair pulling.

Q: Which disorder is characterized by fear of contamination, counting behaviors, and having to check and recheck?

Obsessive-compulsive disorder. ***Obsessive-compulsive disorder*** - This disorder is precisely characterized by repetitive, intrusive thoughts (obsessions) like **fear of contamination** and repetitive behaviors (compulsions) like **counting** and **checking** performed to reduce anxiety associated with these thoughts. - The individual feels compelled to perform these rituals to prevent a dreaded event or situation, even if they recognize the irrationality of their actions. *Panic disorder* - This disorder involves recurrent, unexpected **panic attacks** that cause intense fear and physical symptoms such as palpitations, shortness of breath, and dizziness. - It does not primarily involve obsessions about contamination or compulsive checking behaviors. *Agoraphobia (without panic attacks)* - This condition involves significant anxiety about being in places or situations from which escape might be difficult or embarrassing, or where help might not be available in case of incapacitating or embarrassing symptoms. - It is often associated with fear of public transportation, open spaces, enclosed places, standing in line, or being in a crowd, and does not typically involve contamination fears or repetitive checking. *Generalized anxiety disorder (GAD)* - GAD is characterized by persistent and excessive worry about a variety of daily life events or activities, such as work, finances, or health. - While it involves chronic anxiety, it does not typically manifest with specific obsessions like contamination or compulsive behaviors such as counting and checking.

Q: In which of the following conditions is behavior therapy considered most effective?

Obsessive-Compulsive Disorder (OCD). ***Obsessive-Compulsive Disorder (OCD)*** - **Exposure and Response Prevention (ERP)**, a type of behavior therapy, is the gold standard and most effective treatment for OCD. - ERP directly targets the **obsessions** and **compulsions** by gradually exposing individuals to feared situations without allowing them to perform their rituals. - OCD shows the **highest response rates** to pure behavior therapy compared to other psychiatric conditions. *Psychosis* - While supportive therapy and cognitive behavioral therapy for psychosis (CBTp) can be helpful, **behavior therapy alone is not considered the primary or most effective treatment** for core psychotic symptoms. - Management of psychosis primarily relies on **antipsychotic medications** to address symptoms like hallucinations and delusions. *Panic Attack* - Behavior therapy and CBT are effective for **Panic Disorder**, but the effectiveness is somewhat lower than for OCD. - Treatment for panic disorder often requires a **combination of behavioral and cognitive techniques** rather than pure behavior therapy alone. - Management typically includes breathing exercises, exposure to physical sensations, and cognitive restructuring. *Generalized Anxiety Disorder* - **Cognitive Behavioral Therapy (CBT)**, which includes behavioral components, is highly effective for GAD, but the **cognitive elements are essential** for addressing worry and rumination. - Pure behavior therapy (e.g., systematic desensitization) is less effective for GAD compared to OCD, as GAD involves pervasive cognitive distortions that require cognitive restructuring.

Q: In obsessive-compulsive disorder, which medication is least likely to be prescribed?

Haloperidol. ***Haloperidol*** - **Haloperidol** is a **first-generation antipsychotic** primarily used to treat psychotic disorders like schizophrenia or severe agitation, not OCD as a primary treatment. - Antipsychotics are generally not indicated for OCD unless used as an **adjunctive treatment** in very severe, treatment-resistant cases, or if there's comorbidity with a psychotic disorder. *Clomipramine* - **Clomipramine** is a **tricyclic antidepressant (TCA)** that is a potent serotonin reuptake inhibitor. - It is one of the **oldest and most effective medications** specifically approved for the treatment of OCD. *Sertraline* - **Sertraline** is a **selective serotonin reuptake inhibitor (SSRI)** and is a first-line treatment for OCD due to its efficacy and favorable side-effect profile. - It is commonly prescribed to increase **serotonin levels** in the brain, which helps reduce obsessive thoughts and compulsive behaviors. *Fluoxetine* - **Fluoxetine** is also an **SSRI** and is a first-line medication for OCD. - It is widely used to manage OCD symptoms by enhancing **serotonergic neurotransmission**.
